Answer:
Lucy must walk up 80 steps to reach the 6th floor.
Step-by-step explanation:
Since Michael was 1.0 meters tall, and could only reach up to the 1st floor lift button, and from the 1st floor, he had to walk up 100 steps to reach the 6th floor; while Vinh was 1.4 meters tall, and could reach the 5th floor button, and he had to walk up 20 steps to reach the 6th floor; If Lucy was 1.1 meters tall, to determine how many steps did she have to walk up to reach the 6th floor, the following calculation must be performed:
1 = 100
1.4 = 20
1.4 - 1 = 100 - 20
0.4 = 80
0.1 = X
0.1 x 80 / 0.4 = X
20 = X
100 - 20 = 80
Therefore, Lucy must walk up 80 steps to reach the 6th floor.
You look to the right when you round
A centimeter ruler is more precise because it is a smaller measurement
Yes, there is a difference between 51 and 51.0 because you now know that there is a 0 behind 51 and it was not rounded to become 51.
Units can be helpful because they can help you picture the world problem or convert any numbers like feet to inches properly.
Answer:
A. x^2+6x-15
Step-by-step explanation:
(3x^2+2x-8)-(2x^2-4x+7) distribute the negative sign
3x^2+2x-8-2x^2+4x-7 combine like terms and simplify leaves us with the answer;
x^2+6x-15
